XC RACE LIGHT

HEI HEI SUPREME

Winner of the Mongolia Bike Challenge, the BC Bike Race and TransRockies, the Kona Carbon Hei Hei Supreme is about as much fun as you can possibly have on a 100mm dual-suspension XC race bike. Designed around our quick and efficient yet surprisingly plush Beamer Independent Suspension, with a short, laterally stiff, super-speedy rear triangle, the Kona Carbon Race Hei Hei Supreme is an amalgamation of everything we’ve ever learned about going fast on singletrack. Featuring Stealth dropper post routing and top-drawer components, this year’s model is all about annihilating the competition with a big ol’ smile.

TECHNOLOGY

XC RACE LIGHT

Super fast and really fun: that’s how we like to describe our 2015 lineup of Race Light XC bikes. Since cross-country legend Joe Murray designed some of our first bikes back in 1988, we’ve always been focused on creating incredibly light, ridiculously fast mountain bikes. But what differentiates us from the competition is our want to ensure our bikes deliver equally on the smile quotient. From our technically capable Hei Hei series of dual-suspension trail igniters to the legendary ride of the Kahuna hardtails, no one puts more fun into going fast than Kona.

WHEN DO WE CHOOSE CARBON?

The first step in the design phase is ensuring how carbon fiber can be optimized for its intended use. An increasingly refined and tested material, carbon fiber is the ideal choice when it comes to creating light, tough, playful bikes. While we’re selective when choosing carbon fiber for a given application, for certain models it provides that perfect balance of weight, strength, frame damping, stiffness, compliancy and durability.

DESIGNING THE KONA RIDE

It’s imperative that key elements of the Kona Ride come to life in our carbon bikes. Like with all of our designs, it is efficiency, agility, comfort, and overall strength that are key considerations. We work to leverage all the inherent properties of the material, which are markedly different than steel or aluminum. For our designers it’s crucial that our carbon bikes still feel, ride and last like a Kona.

SMART FABRICATION

THE WEAVE: Kona Carbon bikes use TORAY fibers, the most technologically advanced in the industry. Toray is the same weave used in Formula 1 cars. Our entire structure is built with unidirectional prepreg carbon fiber underneath a UD frame finish. The result is frames with industry-leading weight, stiffness and durability.

THE FRAME: Kona Carbon frames are built with a monocoque main triangle that allows continuous fibers at tube junctures, resulting in a stronger, lighter overall structure. Our production process also eliminates as much bonded-in aluminum inserts as possible. Kona Carbon frames are only molded with internal air bags, which are removed after the molding process.

TORTUROUS TESTING

During the prototyping process, our frames are tested on veritable bike torture machines that push our designs through tens of thousands of test hours. What we learn from this directly translates into making stronger frames, while eliminating unnecessary material. Kona Team athletes are next on the beat down list, but even after they’ve had a rigorous go, our product team steps on to abuse the same prototypes, day-in and day-out, usually through a cold and wet Washington winter.

INTERNAL HEADSET

The major benefit of an internal headset, whereby the bearing cups are actually pressed into the frame and are easily removable, is the extra layer of protection it provides the bearings against the elements. Additionally, the bearings are commonly available angular contact bearings, which are easily and inexpensively replaced. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible.

TAPERED HEADTUBE

Aside from improving the aesthetic, due to its cleaner lines and smooth transition between the fork crown and the headset cover, tapered headtubes also offer a more solid interface between forks with tapered steertubes and the bicycle frame itself, thanks to more weld contact area. More girth at the bottom of the headtube better distributes shock force, prolonging the bearing life of the headset itself, eliminates brake shudder, all while providing positive steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered headtube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it’s needed.

TUBELESS COMPATIBLE RIMS

An increasing amount of 2015 Kona models feature the benefits of tubeless compatible rims. Tubeless rims allow for tires with more puncture resistance, better tire grip on the trail, lower rolling resistance and weight savings over traditional tube + tire systems. For 2015, you’ll find tubeless compatible rims on most of our XC Race Light and Enduro bikes, as well as throughout our Cyclocross and Road platforms.

12X142 REAR AXLES

The XC/Trail/Enduro 12x142mm and the DH 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142mm/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. The take-away? 12x142 and 12x157 standards make a bike that rides better and is easier to work on.

BEAMER INDEPENDENT SUSPENSION

Designed to be off-the-top progressive, helping the bike to stay higher in the travel and recover from hits more quickly, and imbued with what our product managers like to call “pure shock movement,” whereby the shock is protected from side load, Beamer is featured on our super-playful Carbon Operator platform, and the fast but fun MTB Race Light Hei Hei dual-suspension bikes.
